## What it is
A tutorial repository teaching Linux command-line text processing with tools like grep, sed, awk, perl, and ruby one-liners. It has been archived, with its chapters converted into standalone ebooks by the same author.

## Use cases
- learn grep and ripgrep for text search
- learn sed search and replace
- learn awk text processing
- practice regex on the command line
- learn to sort and deduplicate text files
- find command-line tools for text manipulation

## When to avoid
- you need actively maintained content updated for the latest tool versions
- you want polished formatting, exercises, and solutions - use the author's ebooks instead
- you need non-GNU/Linux platform coverage
